Super Battle Golf mod — IssaMod — custom items, tiers & multiplayer (BepInEx)

IssaMod adds chaotic, weaponized gameplay through custom items (airstrikes, missiles, weapons, and physics modifiers), world modifiers, and cinematic strike abilities. It adds 27 new items to Super Battle Golf — from an orbiting gunship you pilot from above, to a pack of angry attack bears. All items drop from standard item boxes and are fully configurable.

Frozen Fairway update (author note)

Release v0.0.25 re-enables IssaMod / IssaPlugin up through Hotfix 4 of the Frozen Fairway update. The mod is very under-tested at this point, so there are likely bugs and strange interactions with the new game mechanics. Custom items also appear in the pause menu, but their spawn weights are not updated properly — the author states this will be addressed in a future update.

Items (overview)

The following are the custom items described by the mod author. Names and behaviour can change with updates — treat in-game behaviour as final after patches.

⚾ Baseball Bat

A melee weapon that replaces your golf club swing. Wind up and send anyone in range flying. Straightforward, personal, deeply satisfying.

🛩️ AC-130 Gunship

You become the gunship. The plane circles the map at altitude while you stare down a targeting camera and rain rockets on your friends. Fire is free, ammo is infinite, and the only limit is how long you can stay on station (and the configured time limit). Hit the mayday button and the gunship nosedives — opponents can lock onto it with a rocket launcher and shoot it down before it reaches them. If they cannot, the crash does the work for you.

💣 Stealth Bomber

Paint a target on the course from ground level, then confirm the strike. Moments later a B-2 roars overhead and carpets the area with bombs. Great for punishing anyone who stops moving. The bomber itself is a valid rocket launcher target — lock on before the run completes to intercept it.

🎯 Predator Missile

You pilot the missile. It drops from altitude and you steer it directly with your camera from a first-person view until it hits something or you let go.

⚛️ Nuke

Drop a nuclear bomb that blows all of the other players sky-high.

🍩 Giant Flying Donut

A massive donut spawns and you pilot it around the course from a third-person perspective. It follows the terrain at low altitude, fires downward lasers as it passes over players, and can be shot down with standard weapons. Equal parts absurd and devastating.

🐻 Attack Bears

Summons AI-controlled battle bears onto the course. Bears chase down the nearest player, wind up, and launch them like a ball. They take damage from all weapons — guns, clubs, the bat, rockets, explosions — and become more aggressive when they get hit. Bears are persistent until killed, which means your bears are everyone’s problem. And your own.

🧊 Freeze World

Turn the world into ice and watch as everybody helplessly slips around.

🌌 Low Gravity

Reduces gravity across the entire course for a configurable duration. Shots fly further, players float on hits, and any ball already airborne gets a free extension. Can backfire badly on anyone with a long putt already in motion. The swing preview / power bar is adjusted during low gravity.

🎯 M200 Intervention

A scoped sniper rifle. Right-click to zoom and show the scope overlay. Fire to hit instantly at any range without the backwards knockback dive of the Elephant Gun. Tight spread when scoped, normal spread when hip-fired. One shot, one hole in someone’s plan.

⚡ Javelin

Locks onto a ground target point and flies a lofted arc: up, turn at apex, dive straight down.

💥 Sticky Grenade

Thrown with an arc preview so you know exactly where it is going. Sticks to whatever it lands on — terrain, structures, or a player who was not paying attention. Detonates on a fuse. If it sticks to a player, they have a few seconds to contemplate their choices.

🌀 Black Hole Grenade

Thrown with an arc preview. Lands and opens a black hole that pulls every nearby player and object toward its center for several seconds, then violently ejects everything outward in random directions. Good luck putting after that.

🧱 Placeable Wall

Plants a destructible brick wall wherever you are standing. Useful for blocking shots, redirecting players, or making the course more chaotic. The wall takes damage from rockets, explosives, golf clubs, and the baseball bat — it will eventually come down, but it might save you long enough to matter.

🔫 AK-47

A rapid-fire sub-machine gun. Hold the fire button and spray bullets downrange at high speed. Each bullet hits independently, so sustained fire on a target adds up fast. Accuracy degrades with range, so this one rewards getting close.

🔄 Position Swap

Pick any other player from the chooser overlay. Warning circles appear around both of you while a short countdown runs — then you swap positions in a burst of smoke. Great for dumping someone into a bad lie or pulling yourself out of one. Cannot be used on players sitting in a golf cart.

🧪 Poison Jar

Lob a jar of poison with an arc preview. On landing it shatters and douses anyone within the blast radius — including you, if your aim is bad. Poisoned players suffer a full screen of visual distortion: camera roll, FOV breathing, double vision, and aim drift that makes lining up a shot genuinely difficult. The radius and duration are configurable.

🛸 Drone Swarm

Deploys a swarm of kamikaze drones that fan out overhead and circle the course. Each drone flies independently with erratic steering, then picks a random target and dives. They home in until they get close, then lock their aim point and fly straight — a fast-moving target can dodge. Swarm size scales with player count. A HUD counter shows how many drones are still airborne.

🐂 Red Bull

Gives you wings. Cracks open a can and grants a speed boost more powerful than coffee, plus a jump height boost for its duration. Use it to cross the course fast, escape a bad situation, or make yourself a harder target to hit.

🍩 Super Donut

Trigger an orbital laser on all other players at the same time.

🌗 Gravity Gun

Like the iconic weapon from the Half-Life franchise — use the Gravity Gun to throw players and golf carts around with ease.

✈️ Harrier Jet

Calls in an autonomous Harrier jet that flies in from off-map, hovers over the course, and fires rockets at players on its own. No steering required after activation — you point and watch. Can be shot down with a rocket launcher before it finishes its run.

🚀 Rocket Tether

Targets another player and fires a rocket that spawns directly above them, then launches straight up. The target is tethered to the rocket by a spring force and gets dragged skyward with it. When the timer runs out, the rocket detonates at altitude.

🎒 Jetpack

Strap on a jetpack and hold the fire button to thrust upward. Each canister provides a set amount of burn time; releasing the button pauses fuel consumption, so you can pulse the thrust. A fuel gauge HUD shows how much burn time is left in the current canister.

📡 Teleporter

The camera pans to a top-down overhead view of the course and a glowing marker appears on the ground. Move the marker with WASD to pick your destination, then confirm to teleport there instantly. Right-click or Space to cancel.

🥬 Spinach

Eat your vegetables. Provides a boost to movement speed and swing power.

🔥 Flamethrower

Unleash a continuous stream of fire in front of you. Enemies caught in the flames run around while they are set ablaze before falling and rolling on the ground.

🚀💣 Rocket Tether Grenade

Throw a toy rocket at the ground, causing a small spark. Anybody within range will be tethered to a rocket — like the Rocket Tether item, but even more chaotic.

💨 Wind Storm

Create a wind storm with extremely high-speed winds and dynamically changing directions. These winds blow away players and golf balls alike.

Installation

• Install via Thunderstore Mod Manager or r2modman. Requires BepInEx.
• Manual install: drop IssaPlugin.dll and IssaModBundle into BepInEx/plugins/ (paths may vary slightly by manager — follow the package readme).

Configuration

In-game spawn config UI (recommended)

The host can open the Spawn Config panel during a session by pressing M (default; rebindable in the config file). The panel configures the tiered item spawn system without editing files by hand. Clients can see the panel in read-only mode; their view updates when the host applies changes.

How the tiered spawn system works

Items are sorted into up to 5 tiers. When an item box is ready to award a custom item, the game first picks a tier by weight, then picks a random item from that tier. This gives coarse control (how common is this whole category?) and fine control (per-item tuning) without balancing every item against every other item directly.

Tier settings (one set per tier):

Setting	What it does
Tier enabled	Master switch for the whole tier. Disabled tiers are skipped entirely.
Spawn weight	How likely this tier is to be chosen. Weights are relative — if Tier 1 is 70 and Tier 2 is 30, Tier 1 is chosen 70% of the time.
Min distance behind leader	Tier only activates for players at least this many units behind the current leader. Set to 0 to lift the restriction.
Min place to trigger	Tier only activates for players in this place or worse (e.g. 3 = 3rd place and below). Set to 0 to lift the restriction.

Both gating conditions must be met simultaneously. Either can be disabled by setting it to 0. This supports “rubber band” tiers that only give powerful items to players who are losing badly.

Per-item settings (in each tier’s item list):

Setting	What it does
Enabled	Removes this item from the spawn pool when unchecked.
Override weight	Gives this item its own spawn weight instead of sharing the tier’s weight equally.
Move →	Reassign the item to a different tier. Weight override is cleared so it inherits the new tier’s weight.

Global settings (top row of the panel):

Setting	What it does
Custom items enabled	Master switch for all custom items.
Global rate multiplier	Scales spawn rate of every custom item. 1.0 = normal; 2.0 = twice as often.
Catchup boost	Extra multiplier applied only to players behind the leader. 1.0 = no boost.
Tiers (+ / −)	Add or remove tiers. A tier can only be removed if it has no items assigned.

Applying changes: click Apply & Sync to save to the config file and broadcast to all clients. Click Cancel to discard and close. Settings persist in BepInEx/config/com.scusemua.IssaPlugin.cfg.

Item-specific settings (config file)

Every item has tuning values in the config file (or via AtomicStudio’s ModConfig mod for an in-game UI): uses per pickup, give key for testing, damage, knockback, duration, speed, range, and other item-specific knobs.

Compatibility

• Multiplayer: All items are networked; the host is server-authoritative. Clients need the mod.
• Base game items: No vanilla items removed or rebalanced — this mod adds.
• Other mods: Should work alongside mods that do not patch the same inventory or item-spawn hooks. The author calls out compatibility with AtomicStudio’s ModConfig and ItemSpawner. Host settings can change mid-session and take effect the next time the associated item is used. Spawn pool weights sync on an interval (author: about five seconds).

Console commands (author)

• vote <timeout> — Host only. Starts a vote to enable or disable individual custom items. Timeout is seconds before the vote closes automatically.
• spawnConfigUI — Opens the tiered spawn config panel (same as pressing M).
• giveCustomItem <item name> — Give yourself a custom item.

Known issues / notes

• The Donut, AC-130, and Stealth Bomber are valid rocket lock-on targets — intentional.
• Hitting a golf ball with a fully charged baseball bat can send the ball backwards (as of the Frozen Fairway update).
